摘要：

A variety of two-dimensional and three-dimensional ZnO nanostructures induced by five types of twinning have been synthesized using a thermal evaporation approach. Self-assembled ZnO nanostructures induced by [01 (1) over bar(1) over bar]/{01 (1) over bar2} and [2 (1) over bar(1) over bar3]/{(2) over bar 112} twinnings are dominant in the products. ZnO nanostructures self-assembled by [03 (3) over bar(2) over bar]/{01 (1) over bar3}, [01 (1) over bar2]/{01 (1) over bar1} and [4 (2) over bar(2) over bar3]/{(2) over bar 114} twinnings constitute a low fraction of the total. The sizes of the self-assembled ZnO nanostructures are determined by the polarity-induced fast [0001] growth of the ZnO nanoneedle building blocks. The configurations and morphologies are determined by twinning type. Twinning is proved to be an effect method to self-assemble ZnO nanoneedle building blocks into two-dimensional and three-dimensional nanostructures with different configurations and morphologies.
